Scala for the Intrigued
 
01:42:04
Are you a Java developer who's curious about Scala? Well, then this talk is for you. We start with an overview of the language, consider some its key strengths, and (of course) take a look under the hood at some serious syntax and code! Venkat Subramaniam, programmer and author, has experience working and teaching in a bunch of different languages (from C++ and Java to Ruby and Erlang). His passion for software development eventually guided him to Scala. Why should we look at a language like Scala? Venkat explains simply, to an audience at SF Java, "because it's fun!" **For more free Scala developer resources: https://marakana.com/s/tags/scala

Scala & Kolacny Brothers - Respire
 
03:39
Album: Respire Released: November 4, 2004 Video: 2005 Scala's version of the French hit Respire (Breath) by Mickey 3D. This song is about a future when mankind has depleted all of our natural resources and the world which we live in is bleak. The original video from Mickey 3D is a beautiful animation that should not be missed (watch it to the end). You can view it here: http://youtube.com/watch?v=Ms4mru6rRl0 (includes English subtitles). Scala recreates the emotions from the original with a more aggressive tone, yet remains loyal to the story being told. -- Lyrics (translated from French) -- Come closer boy, listen to me kid, I'm going to tell you the story of Mankind At first there was nothing, and all was well Nature just grew and spread out, with no paths or roads, Then Man arrived with heavy boots, Kicking Nature in the face, to force respect Tracing one way roads, Installing signposts throughout the plains, Mastering all the forces of Nature Within the blink of an eye was the story changed And we're not about to reverse the trend We've even started to pollute the desert You've got to take a deep breath (breathe), and that's the truth, You're not going to die of laughter, and that's gotta be said In a few years, we'll have cut down all the trees And your grandkids will only have one eye In the middle of the forehead and they'll ask Why you have two eyes, and you'll look like a fool They'll ask you how you were able to sit back and allow this to happen You'll try to defend yourself, explaining in a low voice That it's not your fault but the fault of the Elders Yet there will be no one left to clear you of blame You'll tell them about the days when you could Eat fruits, lying in the grassy fields There were animals all over the forest, When Spring begun, all the birds returned once again, You've got to take a deep breath (breathe), and that's the truth You're not going to die of laughter, and that's gotta be said You've got to breathe, tomorrow it will all get worse You're not going to die of laughter, and that's gotta be said You've got to take a deep breath (breathe), and that's the truth, You're not going to die of laughter, and that's gotta be said [2x] The worst part of the story is that we are all slaves Part of us, an assassin, and here quite unable To look at the trees without feeling guilty Like someone with his pants down, feeling misery 100% So this, my boy, is the story of Mankind It's not very pretty, and I don't know the ending, You weren't born in a cabbage patch, but instead in a hole That we fill day by day, like a manure pit You've got to take a deep breath (breathe), and that's the truth, You're not going to die of laughter, and that's gotta be said [2x] You have to breathe [4x]

Scalable task distribution with Scala, Akka and Mesos
 
45:09
With evergrowing numbers of servers in our data centers, operating these servers has become a complex task. In addition there is a trend towards writing microservices instead of monolithic systems, because they are easier to maintain and deploy independently. Because of the fewer resources such a microservice needs, we traditionally divide our large servers into smaller pieces using VMs, which leads to even more servers that need to be operated.Mesos takes a different approach. Instead of dividing server nodes into smaller pieces, it creates a pool of all the resources in the cluster. These resources can then be used by all applications in the cluster, very similar to a threadpool on a local machine. This makes it easy to create fault tolerant, heterogeneous systems, because tasks do not have a fixed amount of resources allocated to them. They get their resources assigned on demand.In this talk, we will learn how the distributed init and control system Marathon (https://github.com/mesosphere/marathon) utilizes Scala and Akka to reliably deploy applications in a cluster and how it ensures that a configured number of instances is always running. In addition, we will see how Marathon coordinates rolling upgrades of hierarchical application groups with interdependencies and makes sure that a minimum number of instances is kept running to serve the incoming requests and how it prevents faulty deployments from destroying the cluster. Author: Dario Rexin As a Distributed Systems Engineer at Mesosphere, Dario is working on software that simplifies data center management and maximizes resource utilization and fault tolerance. Before joining Mesosphere in April 2014, Dario worked in the Data Science Team at XING, where he developed recommendation and graph analysis systems. He completed his B. Sc. in Computer Science at the University of Applied Sciences in Hamburg. His thesis was focused on building scalable and fault tolerant systems.

Type Members vs Type Parameters - NE Scala 2016
 
23:41
Scala's type system provides generics in two ways: type members and type parameters, and most advanced Scala developers will use both in their code at different times. But how do we choose between them? Usually one or the other will feel "right" for a particular use case, and—if not—we can usually refactor and take the alternative approach. But could we learn to be better at making the "right" choice first time? I'll explore the most important considerations when choosing between them, and look at whether they are completely interchangeable in all cases, or whether certain scenarios force us down one path or the other.

Tutorial: Typeclasses in Scala with Dan Rosen
 
29:57
In this video tutorial, I'll go over the "typeclass" design pattern in Scala, a very powerful technique for keeping your software architectures modular, decoupled and open to extension. Originally implemented as a Haskell language feature, the typeclass pattern in Scala leverages implicits to achieve additional flexibility and control. This video is aimed at developers with some basic experience in Scala and assumes a bit of background with algebraic data types (sealed traits and case classes), implicits and general object-oriented design. ** for more free Scala resources, head to http://marakana.com/s/tags/scala

Scala Collections: Why Not?
 
45:42
Paul Phillips is a co-founder of Typesafe and the most prolific committer to Scala. He's spent the last 5 years developing the language, writing a lot of code and drawing a lot of conclusions, but has decided to walk away. In this talk, he explains why. He outlines what he believes to be certain shortcomings of the Scala collections library. In Paul's words, "Based on my extensive experience with Scala collections, I'm writing my own. The focus is much tighter: immutable, performant, predictable, correct. The talk will alternate between why the Scala collections manage none of those things, and how I hope to do better." A day after the SF Scala event, Paul left this comment on their meetup page, which seems relevant, "[...] I already discovered that if I say nothing about it then people will draw very incorrect conclusions about what the major issues are and why I've moved on. It's not sad, it's not happy, it's only a question of whether you want the real picture or some distant reflection of it."

Functional Programming in Scala
 
37:45
After 10 years of Object Orientated Java, 2 years of Functional Programming in Scala was enough to convince me that I could never switch back. But why? The answer is simple: Functional Scala lets you think less. It reduces the number of moving parts you need to hold in your head, lets you stay focussed and saves your mental stack from overflowing. In this talk I'll show you how to stop treating Scala as a better Java and start exploring the world of Functional Programming. I'll use code examples to demonstrate a four step path that'll let you ease yourself into the world of Functional Programming while continuing to deliver production quality code. With each step we'll learn a new technique, and understand how it leaves you with less to think about: Hopefully this talk will convince you that Functional Scala leads to code that's easier to hold in your head, and leave you excited about learning a new paradigm.

Beyond Scala Lenses—Julien Truffaut
 
45:37
A Lens is a functional concept which solves a very common problem: how to update a complex immutable structure. This is probably the reason why Lenses are relatively well known in functional programming languages such as Haskell or Scala. However, there are far less resources available on the generalization of Lenses known as "Optics". I would like to go through a few of these optics, namely Iso, Prism and Optional. My goal is to show how they relate to each other and how they can be used in common programming tasks. Slides: http://www.slideshare.net/JulienTruffaut/beyond-scala-lens

Dependency Management in Scala: Now and Later
 
34:06
Scala keeps Java's dependency management, with metadata fetched on demand from central repositories. This makes it difficult to mirror, publish releases, reliably cache, and efficiently build. The metadata is limited, with no compatibility data. The lack of this data led to the cross-versioning hack now used to publish for multiple Scala versions. Typesafe's Mark Harrah, creator of the Scala build tool sbt, describes current limitations, suggests some improvements, and offers a few tips. He proposes a future system that addresses compatibility, builds on distributed version control of metadata, and has a mechanism for working with the existing standard. ** More free Scala resources, everything from the 2012 and 2013 Northeast Scala Symposiums, and professional training all available at http://bit.ly/nescala13

RxJava: Reactive Extensions in Scala
 
01:21:22
RxJava is a library for composing asynchronous and event-based programs using observable sequences for the Java VM that supports Java 6+, Clojure, Scala, Groovy, JRuby, and Java 8 lambdas. The Netflix API uses RxJava. So Ben Christensen and Matt Jacobs, of their Edge Surfaces Team, stopped by SF Scala to tell you all about it. They explain what they've done to bring it to the JVM, with Scala, and how they've used RxJava to implement highly concurrent web services against asynchronous data sources without blocking, synchronizations or thread-safety concerns by using declarative functional reactive composition. Find out what RxJava is all about with these real-world examples from Netflix's innovative API.

Explore the Deeplearning4j library and Scala
 
14:02
For links to resources, visit https://developer.ibm.com/tv/explore-deeplearning4j-scala/ Romeo talks with deep learning engineer Francois Garillot about how DeepLearning4J, a Java™ library that helps you compose deep neural nets, links to Scala, Python, Keras, Theano, and TensorFlow. First noticing the stairway in the École polytechnique fédérale de Lausanne is surprisingly similar to the Scala logo (Martin Odersky invented Scala here), Romeo then talks with Skymind Deep Learning Engineer Francois Garillot who principally develops JVM libraries for deep learning and discusses Deeplearning4j, a library that allows you to perform deep neural network training on Apache Spark and GPUs using Java™, Scala, and Python. Francois also develops deep learning models for organizations. Deeplearning4j is the first commercial-grade, open-source, distributed deep learning library written for Java™ and Scala. Integrated with Hadoop and Spark, it is designed to be used in business environments on distributed CPU and GPU clusters. Silicon Valley based startup Skymind is its commercial support arm. Deeplearning4j lets you compose deep neural nets from different types of layers like restricted Boltzmann machines, autoencoders, convolutional or recurrent nets as needed in a distributed, production-grade framework that works with Spark and Hadoop on top of distributed CPUs or GPUs. Francois explains that the higher-level deep learning framework like Keras gives users access to lower-level frameworks like TensorFlow and Theano. Deeplearning4j, the library written for Java™ and the JVM lets the programmer access those features as well from a high-level Python script, but makes use of JVM features like interoperability, functional programming, and strong static type system attributes of a language like Scala. According to Francois, with a library like Deeplearning4j: “We are translators between lots of systems and our Swiss Army knife to do that is the JVM.” Resources for you - Explore Deeplearning4j, the open source, distributed, deep learning library for the JVM - Romeo provides Deeplearning4j examples on GitHub - Use this article as an introduction to deep learning and long-short term memory networks - Learn about Watson machine learning - Explore Watson machine learning on Bluemix - Learn whether to choose deep learning and how to select the right model for your cloud - Here’s a Python notebook that shows you how to use deep learning to build a classification model - Try Bluemix for free

RDDs, DataFrames and Datasets in Apache Spark - NE Scala 2016
 
48:05
Traditionally, Apache Spark jobs have been written using Resilient Distributed Datasets (RDDs), a Scala Collections-like API. RDDs are type-safe, but they can be problematic: It's easy to write a suboptimal job, and RDDs are significantly slower in Python than in Scala. DataFrames address some of these problems, and they're much faster, even in Scala; but, DataFrames aren't type-safe, and they're arguably less flexible. Enter Datasets, a type-safe, object-oriented programming interface that works with the DataFrames API, provide some of the benefits of RDDs, and can be optimized via the Catalyst optimizer. This talk will briefly recap RDDs and DataFrames, introduce the Datasets API, and then, through a live demonstration, compare the performance of all three against the same non-trivial data source.

Intro To Kotlin: Kotlin Android Tutorial
 
07:46
*Kotlin is an official language for Android development not a replacement of java. You should still learn Java first if you do not know it!* I recently started learning Kotlin on Android. A lot of people are thinking in terms of Java vs Kotlin but I have learned that Java and Kotlin are best viewed as friends meant to work together (better yet, teammates). In this video ,I will talk a bit about why Kotlin is awesome, how it plays with Java and how you can start using it today. In the future, I hope to continue sharing some of the things I am learning and hopefully making some Kotlin Android tutorials. Sidenote: I am BRAND NEW to functional programming so teach me something in the comments section that you care to share :) Try Kotlin now: https://try.kotlinlang.org Useful videos from the makers of Kotlin: Kotlin videos, tutorials and resources: http://kotlinlang.org/docs/reference/ My coworkers talk on Kotlin: https://www.youtube.com/watch?v=mDpnc45WwlI And her Android Dialogs talk on Kotlin: https://www.youtube.com/watch?v=xRDqDe4rxkM&t=109s Follow me on Twitter: https://twitter.com/MadeyBytes

Radioactive Scalar Pendant Quantum Scalar Energy Pendant - Are They Radioactive?

PLEASE SUPPORT my EMF Safety Zone Channel! Any size contribution is appreciated! https://paypal.me/NeilSCohen?locale.x=en_US - EMF Meters, Consulting, Resources: https://emf-protection.us - eBay store for EMF meters and related products at the lowest prices: http://www.ebaystores.com/healthyjoyfulsustainableliving Join me on Twitter for educational updates! https://twitter.com/EMFSafetyZone / @EMFSafetyZone I am using a Mazur Instruments PRM-9000 Geiger Counter to measure "ionizing radiation." Ionizing radiation is what emits from radioactive elements such as plutonium, uranium, or other earth-based mineral elements. Ionizing radiation is different than the "non-ionzing" radiation which emits from cell phone towers and other wireless devices such as cell phones or cordless phones. People wear these so called "Scalar Energy Pendants" all over the world, believing they are healthy or they protect them from EMF. You decide for yourself if they are safe or not? I am not an expert on this subject. And there may be a slight possibility that the material used to make these pendants is simply radioactive with the natural earth elements of the black volcanic rock it is made from. To be open minded, I would say there is a chance that the earth-based form of natural radiation may not be as bad as man-made radiation. There are those who believe that small amounts of natural earth-based radiation is healthy for the body. Some people put slightly radioactive rocks into their drinking water. I believe this is called the science of "Hormesis" if I am not mistaking. However, I posted this video so at least people would be educated, warned, take necessary precautions, or they can continue with their own research for a further education.

Linux Command Line Tutorial | Learn the Bash Command Line | Linux Terminal Tutorial
 
05:16:56
Linux is a computer operating system free for development and distribution, both commercially and non-commercially. There are times when you may spend hours doing a repetitive task. A person who knows command line can write a script in 10 minutes and if he has to repeat it, can do it in a second. So what is Command Line and why is it so popular? Command line applications provide us with numerous benefits which cannot be achieved with any of the available GUI applications. One can create scripts to automate work, and can go so much deeper into the system and explore things that would generally be not possible with GUI. This course is designed for beginners who are new to this operating system and have never installed or operated Ubuntu Linux. People thinking about being a Linux system administrator or engineer can use this as the perfect place to start learning the basics from. This is not restricted for these people, anyone who wants to optimize their tasks and make them simpler using command line scripts can take up this course. No prior experience with Ubuntu is necessary. 00:00:00 1 - Introduction 00:07:46 2 - ls command in Linux 00:24:57 3 - cd command in Linux 00:36:19 4 - cat command in Linux 00:45:22 5 - I/O Redirection 00:54:08 6 - mkdir Command 01:00:22 7 - rm and rmdir commands for linux 01:12:37 8 - cp command 01:24:21 9 - mv command 01:35:50 10 - less command 01:43:00 11 - touch command 01:48:00 12 - nano command 01:54:48 13 - sudo command 02:02:49 14 - top command 02:10:42 15 - kill command 02:19:30 16 - echo command 02:27:11 17 - file permissions, symbolic permissions and chmod 02:39:31 18 - directory permissions and chmod 02:46:43 19 - Octal and Numerical permissions (chmod) 02:56:07 20 - Introduction to Bash Scripting 03:05:57 21 - which and whatis command 03:11:11 22 - useradd command (Creating Users) 03:18:08 23 - userdel command (Removing Users) 03:23:03 24 - Basic Group Management (groups, groupadd, groupdel) 03:29:31 25 - .bashrc File 03:36:39 26 - Viewing Resources (du , df, free command) 03:46:25 27 - watch command 03:50:02 28 - Head and Tail Commands 03:56:52 29 - find command 04:04:02 30 - wc command 04:08:17 31 - cal command 04:11:59 32 - date command 04:17:48 33 - How to Run multiple Terminal Commands 04:27:00 34 - apt-get command to Install Software 04:39:21 35 – ifconfig command 04:47:46 36 - tar command to Compress and Extract Files 04:53:36 37 - grep command 05:04:22 38 - netstat command ★★★Top Online Courses From ProgrammingKnowledge ★★★ Python Programming Course ➡️ http://bit.ly/2vsuMaS ⚫️ http://bit.ly/2GOaeQB Java Programming Course ➡️ http://bit.ly/2GEfQMf ⚫️ http://bit.ly/2Vvjy4a Bash Shell Scripting Course ➡️ http://bit.ly/2DBVF0C ⚫️ http://bit.ly/2UM06vF Linux Command Line Tutorials ➡️ http://bit.ly/2IXuil0 ⚫️ http://bit.ly/2IXukt8 C Programming Course ➡️ http://bit.ly/2GQCiD1 ⚫️ http://bit.ly/2ZGN6ej C++ Programming Course ➡️ http://bit.ly/2V4oEVJ ⚫️ http://bit.ly/2XMvqMs PHP Programming Course ➡️ http://bit.ly/2XP71WH ⚫️ http://bit.ly/2vs3od6 Android Development Course ➡️ http://bit.ly/2UHih5H ⚫️ http://bit.ly/2IMhVci C# Programming Course ➡️ http://bit.ly/2Vr7HEl ⚫️ http://bit.ly/2W6RXTU JavaFx Programming Course ➡️ http://bit.ly/2XMvZWA ⚫️ http://bit.ly/2V2CoAi NodeJs Programming Course ➡️ http://bit.ly/2GPg7gA ⚫️ http://bit.ly/2GQYTQ2 Jenkins Course For Developers and DevOps ➡️ http://bit.ly/2Wd4l4W ⚫️ http://bit.ly/2J1B1ug Scala Programming Tutorial Course ➡️ http://bit.ly/2PysyA4 ⚫️ http://bit.ly/2PCaVj2 Bootstrap Responsive Web Design Tutorial ➡️ http://bit.ly/2DFQ2yC ⚫️ http://bit.ly/2VoJWwH MongoDB Tutorial Course ➡️ http://bit.ly/2LaCJfP ⚫️ http://bit.ly/2WaI7Ap QT C++ GUI Tutorial For Beginners ➡️ http://bit.ly/2vwqHSZ ★★★ Online Courses to learn ★★★ Data Science - http://bit.ly/2BB3PV8 | http://bit.ly/2IOrpni Machine Learning - http://bit.ly/2J2xex1 Artificial Intelligence - http://bit.ly/2AeIHUR | http://bit.ly/2PCCBEb Data Analytics with R Certification Training- http://bit.ly/2rSKHNP DevOps Certification Training - http://bit.ly/2T5P6bQ AWS Architect Certification Training - http://bit.ly/2PRHDeF Java, J2EE & SOA Certification Training - http://bit.ly/2EKbwMK AI & Deep Learning with TensorFlow - http://bit.ly/2AeIHUR Big Data Hadoop Certification Training- http://bit.ly/2ReOl31 AWS Architect Certification Training - http://bit.ly/2EJhXjk Selenium Certification Training - http://bit.ly/2BFrfZs Tableau Training & Certification - http://bit.ly/2rODzSK Linux Administration Certification Training-http://bit.ly/2Gy9GQH ★★★ Follow ★★★ My Website - http://www.codebind.com DISCLAIMER: This video and description contains affiliate links, which means that if you click on one of the product links, I’ll receive a small commission.

Scalding: Powerful & Concise MapReduce Programming
 
01:05:29
Scala is a functional programming language on the JVM. Hadoop uses a functional programming model to represent large-scale distributed computation. Scala is thus a very natural match for Hadoop. In this presentation to the San Francisco Scala User Group, Dr. Oscar Boykin and Dr. Argyris Zymnis from Twitter give us some insight on Scalding DSL and provide some example jobs for common use cases. Twitter uses Scalding for data analysis and machine learning, particularly in cases where we need more than sql-like queries on the logs, for instance fitting models and matrix processing. It scales beautifully from simple, grep-like jobs all the way up to jobs with hundreds of map-reduce pairs. ** For more resources, training, and video tutorials on Scala, head to http://marakana.com/s/tags/scala

Zero to 60 in Software Development: How to Jumpstart Your Career - Forward 4 Web Summit
 
31:50
Our industry has a problem. We have a "talent shortage," so we're loading the industry with new developers from various bootcamps, but they're having trouble finding jobs because many companies are unwilling to hire and train them. So these new developers are left to themselves to try and find ways to develop the skills they need to be "marketable." Kent C. Dodds graduated from college in April 2014, just shy of two years ago. In that time, he's been able to learn a ton, build a bunch of stuff, teach workshops, create egghead screencasts, speak at conferences, and generally contribute quite a bit to the JavaScript community. In this talk, Kent covers some solid principles of things that he's learned in his experience. This will help new-comers to jumpstart their career. And help old-timers know how they can help new-comers. Forward Web Summit: http://forwardjs.com/ Training & Resources for Software Developers: https://newcircle.com/

Building a data analytics engine on AWS, the Simple way
 
53:35
Whether you are a smaller startup or a well-established company, data analytics can give you insights that drive engineering and business decisions. How can you build an engine like this, especially if you have limited resources? Once you do build the engine, how can you make sense of the data? These are two critical questions that Jeff Klukas answers for us in this episode. See how Simple built an engine on AWS with Redshift and learn from it. Scale and migrate large workloads after a free month test run on DigitalOcean, and get free Premier Support: https://scaleyourcode.com/digitalocean Already work on AWS and want to learn it inside and out? Get trained at your own convenience for $9 the first month: https://scaleyourcode.com/linuxacademy 1:22 - You were a research assistant for the University of Wisconsin in Madison. Can you tell us a little about what you did there? 4:00 - Now you're at Simple, which is a banking platform. Did you take that experience of automation and finding relationships with data and carried it to Simple? 5:19 - Simple is a banking platform. Can you tell us what it offers? 6:48 - Is that the kind of data that you're working with where you're crunching those numbers and trying to figure out what the "safe to spend" amount is and fraudulent activity and things like that, or are you working on a different set of data? 8:10 - You've built a funnel that receives data from different source and then you sort it out and use Redshift to make sense of that data. Can you walk us through how that's set up? How does Redshift receive data? Where does the data come from, etc? 10:34 - You have both internal and external facing APIs that receive data from different services you're using (like Postgres), as well as from other clients. After that, it goes to the loader which then batches it up and goes to Amazon S3 which then loads it into Redshift. Is that right? 11:05 - Did you build the loader itself? Is it custom built? 15:00 - Why Redshift instead of just leveraging PostgreSQL which you already have, or something like MySQL which a lot of people are really familiar with. What does Redshift have to offer that you can't find in those other engines? 18:08 - Redshift is still SQL based so you can still come from a background of MySQL or Postgres and still have the ability to quickly and accurately pull data. Are there any cons to that or is it all beneficial? 20:30 - Can you talk a little bit more about the distributive nature of Redshift and how it is able to distribute the data and how you know how it's distributing it so you can query more efficiently? 22:38 - Is it really trial and error when you're first getting started with Redshift if you don't have a lot of experience, or is it really understanding how that distributive nature works and then customizing the queries around that and then just trying and seeing which queries take a while and which queries need to be changed? Is that how you approached it? 24:42 - Redshift is actually an Amazon managed service, so are you able to easily plug it into CloudWatch and see some of those performance metrics or bottlenecks that you can quickly try to change or is that using other tools? 26:28 - I assume you can see those system tables in the Amazon Dashboard as well or you can use the API to pull that information and feed it into Grafana or whatever else you're using like that, right? 27:30 - Are you using the same monitoring tools to monitor things like RabbitMQ and Postgres and all those other services in your infrastructure? 28:19 - You also built a tool in Scala that collects and publishes Redshift performance metrics. Can you tell us a little bit more about that? 30:54 - Why Scala? The reason I'm asking this is because with Java 8 we've seen companies like LinkedIn where last I checked, they had moved to Scala and again, moved back to Java, I guess where they didn't see those benefits in performance or even finding the talent was difficult. Why are you using Scala? 33:30 - Do Java developers have a harder time switching to Scala because they use the Java way of doing things? 36:18 - We've been talking a lot about the back-end of this data analytics engine. At one point in time you have to visualize this data, right? How do you do that? 41:30 - How do you actually take the data from Redshift and plug it in to Periscope data? 43:10 - When you build realtime data analytics, how can you make sure that when an executive, engineer, customer, marketing agent or whoever looks at realtime data, that the data isn't skewed?

Programowanie w języku Scala / Moduł 4. Parametryzacja typów i typy generyczne / Cz. 3
 
53:13
Dodatkowe materiały: www.bnsit.pl/devcastzone/SCALA_M4.zip Opis szkolenia: Devcast "Programowanie w języku Scala" wprowadza do programowania w języku Scala. W trakcie trwania poznasz podstawy języka Scala jak również zagadnienia zaawansowane. Po zakończeniu szkolenia, uczestnik będzie mógł rozpocząć samodzielne tworzenie aplikacji z wykorzystaniem Scali. Devcast rozpoczyna się od konfiguracji środowiska programistycznego, a kończy na rozbudowanym systemie typów Scali. Opis modułu: Moduł czwarty dotyczy parametryzacji typów oraz typów generycznych. Zgłębimy się w skomplikowany system typów Scali w celu wykorzystania go do tworzenia aplikacji. Omówiona będzie wariancja typów, ograniczenia górne oraz dolne i widoki.

Testing in Future Space - NE Scala 2016
 
33:34
In ScalaTest 3.0's new async testing styles, tests have a result type of Future[Assertion]. Instead of blocking until a future completes, then performing assertions on the result, you map assertions onto the future and return the resulting Future[Assertion] to ScalaTest. The test will complete asynchronously when the Future[Assertion] completes. This way of testing requires a different mindset. In this talk I'll walk you through the design, show you how to use it, and suggest best practices for async testing on both the JVM and Scala.js.

Scala.js for large and complex frontend apps
 
52:16
Managing complex frontend apps in plain JavaScript is quite painful, especially when it comes to refactoring the source code. Moving to TypeScript helps a bit, but doesn't quite solve the complexity problem. Scala.js allows developers write applications in Scala while retaining full compatibility with existing JS libs. You get the benefits of a type safe, advanced compiled language without needing to abandon all your favorite JavaScript frameworks. In this webinar we introduce Scala.js through practical examples and with comparison to ES6.

Type-Driven Development in Idris — Edwin Brady
 
46:36
Idris is a general purpose pure functional programming language with dependent types. In Idris, types are a first class language construct, meaning that they can be manipulated and computed like any other language construct. It encourages a type-driven style of development, in which programmers give types first and use interactive editing tools to derive programs. Introductory examples typically involve length-preserving operations on lists, or ordering invariants on sorting. Realistically, though, programming is not so simple: programs interact with users, communicate over networks, manipulate state, deal with erroneous input, and so on. In this talk I will show how advanced type systems allow us to express such interactions precisely, and how they support verification of stateful systems as a result. The talk will include several examples, leading to a verified implementation of a word game (Hangman). I will show how Type-driven Development allows programmers to specify the game rules in a direct and concise style, and how it leads to an implementation, guaranteed to correctly follow the rules by typechecking.

Macros for Mortals - NE Scala 2016
 
31:31
Since their introduction in 2.10, Macros have veritably taken Scala by storm. They pop up everywhere, often providing elegant syntax extensions for Scala libraries; note the prevalence of "sql" string interpolation macros, for example. Many developers, however, are scared and confused by Macros – rightly so. Many examples of Macros require deep knowledge of the Scala AST, internals and oddities. But hope exists: newer features like quasiquotes make it ridiculously easy to write powerful Macros with code templating. In this talk, we’ll demystify just how Macros work and are constructed, walking through many of the different "types" of Macros that Scala supports. A final focus will be given to the use of the newer Quasiquotes and Annotations features as a way of quickly constructing powerful new code features in your own Scala code.

Introduction to the Actor Model for Concurrent Computation: Tech Talks @ AppNexus
 
40:52
In this tech talk, John Murray, Senior Software Engineer at AppNexus, serves up an introduction to Actor Model principals and concepts and gives a look at how we can construct parallel systems using the Akka framework. Actor Models is a computational model for designing concurrent, distributed systems around the principal of self-contained Actors which operate on sending and receiving messages. While the idea has been around since the mid to late 70's, it is now gaining more traction with frameworks such as Akka and Celluloid as well as languages such as Go, which share many similar principals.
